Abstract
Image restoration and reconfiguration support for crashed network devices. The method includes establishing a file transfer session between an information transferring network device that has entered a debug mode and a server. A name of a last known good image and configuration file pair is stored on the network device. The last known good image and configuration file pair is stored on the server. The network device requests a transfer of the last known good image and configuration file pair from the server to the network device.
Claims26
A method comprising:
- establishing a file transfer session between an information routing network device that has entered a debug mode and a server, the network device storing an identifier corresponding to a last known good image and configuration file pair stored on the server;
- requesting a transfer of the last known good image and configuration file pair from the server to the network;
- and
- automatically reconfiguring the network device according to the last known good image and configuration file pair from the server.
A method comprising:
- detecting that an information routing network device has entered a debug mode, a name of a last known good image and configuration file pair being stored on the network device;
- establishing a first file transfer session between the network device and a first server, a first image and configuration file pair being stored on the first server;
- determining whether the first image and configuration file pair matches the last known good image and configuration file pair;
- establishing a second file transfer session between the network device and a second server, a second image and configuration file pair being stored on the second server;
- determining whether the second image and configuration file pair matches the last known good image and configuration file pair;
- establishing a second file transfer session with a second server, a second image and configuration file pair being stored on the second server,
- determining whether the second image and configuration file pair is the last known good image and configuration file pair, and
- wherein the method further includes requesting a transfer of one of the first or second image and configuration file pair that is the last known good image and configuration file pair from the server to the network device.
An apparatus comprising a machine accessible medium containing instructions which, when executed by a machine, cause the machine to perform operations comprising:
- establishing a file transfer session between an information routing network device that has entered a debug mode and a server, the network device storing an identifier corresponding to a last known good image and configuration file pair stored on the server;
- requesting a transfer of the last known good image and configuration file pair from the server to the network device;
- and
- automatically reconfiguring the network device according to the last known good image and configuration file pair from the server.
